libredbdiff: Many improvements
* cleaner output format * multiple non-default repositories Parabola: libre pcr libre-multilib nonprism Arch: multilib * a single Parabola repository can be specified as argument to restrict the comparison to that repository * support expac 4 extra/expac 4.2 has a bug, so pcr/expac-relative 4.2-parabola1 or later is needed * detection of missing files * code style * move code to functions * usage text and messages
